They do several tricks where they pretend to reveal what they are doing, revealing how the trick normally works I think, and then proceed to do something that makes it apparent that is not actually what they are doing.

They have a particularly gory version of sawing a woman in half for example. I think it is on youtube somewhere, pretty solid.

But yeah, I don't think you could say that they reveal tricks that "belong" to other magicians. They reveal the basic stuff.
